3 Functions and features

The unit continuously detects the level optically and generates output signals

according to the parameter settings�

3.1 Application areas

• The optical level sensor detects media in the measuring range of

20�0��1000�0 cm� They are displayed in relation to a previously defined refer-

ence level�

• It has a background suppression at > 10��100 m�

• Two output signals can be generated, depending on the function mode�

The distance between the sensor and the background must be limited

to max� 100 m by the customer� Otherwise the measured value may be

ambiguous. → 5.1 Installation conditions

3.2 Restriction of the application area

• The unit is suited for granulates, bulk material and cloudy liquids�

• Dust and vapour can impact the quality of the measurements�

• The unit is not suited for oils and clear liquids�

4 Function

4.1 Switching function

4.1.1 Hysteresis function

The outputs change their switching status when the value is above or below the

set switching limits� The hysteresis is the distance between the set and reset

points� The hysteresis keeps the switching status of the output stable if the meas-

ured value varies about the sensing range�

Both outputs (OUT1 and OUT2) can be set as hysteresis function (→ 10.3.3 and

→ 10.3.6)�

7

UK

Example Hno

1� For the output function [Hno] the output switches on when the set point [SPx]

is exceeded in case of a rising level�

2� If the level falls again, the output switches off as soon as the level is below the

reset point [rPx]� The reset point [rPx] is below the set point [SPx]�

If the output function [Hnc] has been selected, set and reset point are exchanged�

The output switches off for rising level� If the level falls below [rPx] again, the

output switches on�

4.1.2 Window function

The window function enables the monitoring of a defined acceptable range� Both

outputs (OUT1 and OUT2) can be set as window function (→ 10.3.3 and →

10�3�6)�

Switches when the medium is detected

If the measured value is between the lower

limit value [rPx] and the upper limit value

4.2 Analogue function

An analogue signal, which is proportional to the distance, can be provided at out-

put 2 (OUT2) → 10.3.9 Scaling of the measuring range (analogue output)�

4.3 Switch off the laser

4.4 IO-Link

This unit has an IO-Link communication interface which enables direct access

to process and diagnostic data� In addition it is possible to set the parameters of

the unit during operation� Operation of the unit via IO-Link interface requires an

IO-Link master�

With a PC, suitable IO-Link software and an IO-Link adapter cable communication

is possible when the system is not in operation�

The IODDs necessary for the configuration of the unit, detailed information about

process data structure, diagnostic information, parameter addresses and the

necessary information about the required IO-Link hardware and software can be

found at www�ifm�com�

11

UK

4.4.1 Operation with IO-Link master

The unit is compatible with IO-Link master port class A (type A)�

For operation with IO-Link master port class B (type B) observe the following:

As a standard, the unit is not compatible with master port class B (type B)�

Pin 2 (OU2) and pin 5 (IN1) are used for manufacturer-specific functions�

That means that the main supply voltage of the unit and the additional volt-

age supply (master port class B on pins 2/5) are not electrically isolated�

With the following configurations the unit can be used with master port class B:

• Connect unit and IO-Link master via 3 wires: Connect pins 1, 3 and 4 of the

unit with the IO-Link master (do not connect pins 2 and 5)�

• Connect unit and IO-Link master via 4 wires: Deactivate pin 2 (OU2) via IO-

Link (setting OU2 = "off") and connect pins 1, 2, 3 and 4 of the unit with the

IO-Link master (do not connect pin 5)�

4.4.2 Extended functions

By means of IO-Link extended measured data are available�

The object reflectivity is provided via the display and as process data value (PDV)

via IO-Link�

The object reflectivity can, for example, be used to detect sensor soiling�

5 Installation

5.1 Installation conditions

► Install the unit so that the medium to be detected is within a measuring range of

20�0��1000�0 cm�

The unambiguity range of the sensor is fixed to 100 m� Levels within a range

> 10…100 m are suppressed�

Reflecting surfaces in the direct beam path of the sensor – also in the

range > 100 m – are to be avoided by the customer� Otherwise the meas-

ured value may be ambiguous�

5.2 Location

► Mount the sensor in a way that a distance (D) of min� 20�0 cm remains between

the highest possible level and the front lens of the sensor�

► The maximum measuring distance (H) between the front lens of the sensor and

the tank bottom or the programmed level is 10 m� A reference height at a longer

distance cannot be set�

D = min� measuring distance / dead zone
